Abstract
Description
- This application claims benefit of Serial No. 2010-070245, filed 25 Mar. 2010 in Japan and which application is incorporated herein by reference. To the extent appropriate, a claim of priority is made to the above disclosed application.
- The present invention relates to a cylinder liner cast around a cylinder block by insert casting.
- In automobile engines, sometimes a cylinder block made of an aluminum alloy etc. has a cylinder liner made of cast iron etc. cast around it by insert casting. In this case, since the cylinder liner and the cylinder block are different in physical properties, sometimes a clearance etc. forms between the cylinder liner and the cylinder block. To solve this problem, in Japanese Patent Publication (A) No. 2008-8209, the cylinder liner has a thermal sprayed coated film of aluminum or aluminum alloy formed on its outer circumferential surface.
- In Japanese Patent Publication (A) No. 2008-8209, by thermal spraying the cylinder liner at the outer circumferential surface, the adhesion between the cylinder liner and the cylinder block is improved and an improvement in the bond strength and heat conductivity is obtained. However, thermal spraying the cylinder liner at the top surface is not described.
- An object of the present invention is to provide a cylinder liner excellent in adhesion and heat conductivity with a cylinder block.
- To solve this problem, the present invention adopts the following solution to the problem. That is, the present invention provides a cylinder liner cast around a cylinder block by insert casting characterized in that a thermal sprayed coated film is formed at the top surface and outer circumferential surface.
- In the above, the connecting edges of the top surface and the inner circumferential surface are preferably chamfered and the thermal sprayed coated film of the top surface part is formed so as to extend over the chamfering part. The chamfered surface is preferably a slanted surface or curved surface.
- According to
claim 1, when the cylinder liner is cast over not only the outer circumferential surface, but also the top surface, by insert casting, the bond strength and heat conductivity of the cylinder liner and cylinder block are excellent. According toclaim 2, the adhesion of the thermal sprayed coated film at the cylinder liner top surface is improved. According toclaim 3, the adhesion of the thermal sprayed coated film is further improved. -
FIG. 1 is a longitudinal cross-sectional view showing one part of a cylinder liner of the present invention. -
FIG. 2 is a longitudinal cross-sectional view showing a cylinder liner cast over a cylinder block. -
FIG. 3 is a longitudinal cross-sectional view showing a part of another cylinder liner of the present invention. -
FIG. 4 is a longitudinal cross-sectional view showing a part of still another cylinder liner of the present invention. - Below, preferred embodiments of the present invention will be explained with reference to the drawings.
- In
FIG. 1 andFIG. 2 , thecylinder liner 1 is formed from cast iron or steel, while thecylinder block 2 is formed from an aluminum alloy or other light alloy. Thecylinder liner 1 is formed with a thermal sprayed coatedfilm 6 at the outercircumferential surface 3 and thetop surface 4. As the thermal sprayed material, Al, an Al alloy, Fe, an Fe alloy, Zn, a Zn alloy, Cu, a Cu alloy, etc. is used. Thecylinder liner 1 is cast over thecylinder block 2 by insert casting at the outercircumferential surface 3,top surface 4, and bottom surface 5. - Since the cylinder liner of the
present invention 1 is formed with a thermal sprayed coatedfilm 6 at the outercircumferential surface 3 and thetop surface 4, the adhesion and heat conductivity with thecylinder block 2 are excellent. -
FIG. 3 shows another cylinder liner of the present invention. Thiscylinder liner 1 is formed with a chamfering 8 part at the connecting edges of thetop surface 4 and the inner circumferential surface 7. The thermal sprayed coatedfilm 6 is formed at thetop surface 4 part so as to extend over the chamfering 8 part. The chamfering 8 surface is a slanted surface. The rest of the configuration is the same as the above embodiment. - In the present embodiment, the thermal sprayed coated
film 6 is formed so as to extend over the chamfering 8 part of the connecting edges of thetop surface 4 and the inner circumferential surface 7, so the thermal sprayed coatedfilm 6 is excellent in adhesion. -
FIG. 4 shows still another cylinder liner of the present invention. Thiscylinder liner 1 has a chamfering 8 part, formed at the connecting edges of thetop surface 4 and inner circumferential surface 7, which forms an arc shaped surface. The rest of the configuration is the same as the above embodiment. - In the present embodiment as well, the adhesion of the thermal sprayed coated
film 6 is excellent. -
- 1 cylinder liner
- 2 cylinder block
- 3 liner outer circumferential surface
- 4 liner top surface
- 5 liner bottom surface
- 6 thermal sprayed coated film
- 7 liner inner circumferential surface
- 8 chamfering
